BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the field of audio-visual systems. More specifically, the invention comprises a display mount incorporating an integrated audio system.

2. Description of the Related Art

Throughout this disclosure the terms “television” and “video display” are used synonymously. While some persons previously drew a distinction between these two terms on the basis of whether the particular unit included a tuner, this distinction no longer makes sense as most displays now have the ability to serve multiple purposes (such as the ability to serve as a computer monitor and a display of cable or satellite television programming). In any event, the integrated display and audio system disclosed in the present invention function equally well for any of these units.

Video displays are now commonly used for both residential and commercial. purposes. The technology underlying these displays has changed dramatically over the past several years. Picture-tube based displays were previously the standard. Such displays were inherently bulky, with the depth of the unit being comparable to its other dimensions. While the bulk made the units visually unappealing, space within the cabinetry did provide ample volume for the inclusion of integrated audio systems. An older picture-tube television having a diagonal frontal dimension of 40 inches (about 100 centimeters) typically had a cabinet depth of about 30 inches (about 75 centimeters).

With the advent of modern electronics and their inherent space efficiency, much of the cabinet space available in picture-tube televisions was left vacant. A television manufacturer could easily place relatively large speakers (such as 4 inches by 6 inches) in the vacant space within the cabinet. Speakers of this size provided a rich tonal quality to the sound produced.

The prior art changed dramatically when display designed without a picture tube appeared. These are generally referred to as “flat screen” televisions. Examples include liquid crystal displays (“LCD's”) and plasma displays. Flat screen televisions are typically very thin. In fact, limiting the depth of a flat screen television has become a styling goal for most manufacturers. A flat screen television with a diagonal frontal dimension of 40 inches (100 centimeters) may have a depth of less than two inches (5 centimeters). The television's perimeter is typically made even thinner. The perimeter is often less than one inch (2.5 centimeters) thick.

The visual performance of modern flat screen televisions is significantly better than picture-tube based televisions. However, the limited space within the “cabinet” of a flat screen (to the extent one can even call such a thin structure a cabinet) leaves very little room for audio components. The lack of space has forced flat screen manufacturers to use increasingly smaller audio transducers.

Another styling goal of the flat screen manufacturers has been to occupy as much of the forward-facing surface as possible with the video display itself. Thus, the audio transducers which are present are often now in a sub-optimal orientation; that is, the speaker cones face to the side or even to the rear of the television and do not direct the sound energy toward the user. The result is that—while the video performance of these devices has progressed markedly—the audio performance has at best remained stagnant and has in most instances deteriorated.

A consumer buying a high-performance flat screen television often desires a “home theater” experience in which the sound quality is comparable in volume and range to the sound heard in a movie theater. Such a consumer will not be satisfied with the limited acoustic performance of a modern flat screen television. The consumer must therefore bring in additional components to solve this problem.

Audio solutions for home theater systems are widely varied and complex. FIG. 1 gives one simple example. Flat screen display 10 has been mounted on a wall using one of the available mounting systems. Separate components are housed in rack 24 (which may be anything from a simple electronics rack to an elegant piece of furniture designed specifically to conceal the components). Rack 24 typically encloses a cable or satellite decoder box, a DVD player, a video game console, and an amplifier 12. The amplifier may be a sophisticated PRO/LOGIC decoding system (such as offered by Dolby Laboratories of San Francisco, Calif.) that splits the audio signal into at least four channels—typically referred to as left, center, right, and rear (The rear channel is sometimes known as a “subwoofer” channel).

Cables run between rack 24 and flat screen display 10. In this example, a two channel audio cable 14 is run from the television to amplifier 12. In other examples, a single HDMI cable may be connected from the cable box to the amplifier, with a second HDMI cable running from the amplifier to the television. These represent a hard-wired connection between the amplifier and the television.

The speakers are also connected to the amplifier. Left channel speaker 22 is connected via speaker cable 26. Center channel speaker 16 is connected via its own cable (not visible in the view). Right channel speaker 20 and subwoofer 18 are also connected to the amplifier via speaker cables 26.

The system shown in FIG. 1 produces reasonably good audio performance. However, the reader may easily perceive the irony of the situation. In creating ever-thinner flat screen televisions the manufacturers have created an elegant and “clean” appearance for the visual aspects of a home entertainments system. However, in so doing, they have reduced the audio performance of the television itself to an unacceptably low level. The typical response to this problem is the addition of numerous other components and cables which completely destroy the visual aesthetic originally sought.

The present invention seeks to resolve this dilemma by integrating an external audio system into-the television's mount and concealing many of the components of that system behind the television. The reader will benefit from an understanding of existing mounting technology. Modern television mounts fall into two broad categories: (1) wall mounts which attach to the rear of the television; and (2) pedestal mounts which attach to the base of the television. The volume immediately behind the television is not typically used under either approach.

FIG. 2 represents a common wall mounting system for a television. In this example, wall bracket 28 is attached to the wall by passing bracket mounting bolts 36 through the bracket and into the wall studs or masonry. Uprights 32 on TV bracket 30 are attached to the rear of the flat screen television by passing TV mounting bolts 34 through the uprights and into the television. TV bracket 30 is then slidably engaged with wall bracket 28 (with the television attached).

Many other mounting systems exist. The TV bracket in some of these other systems attaches to the wall bracket by pivoting into position rather than sliding. The general concept of having a first portion attached to the wall and a second portion attached to the television is used in nearly every prior art mounting system, and it is in fact preferable to use this approach for the present invention as well.

When using the wall mounting approach, a significant gap typically remains between the rear of the television and the wall itself. This gap is mostly occupied by the mount itself. The present invention seeks to take advantage of this potentially available space by creating a mounting system with at least a portion of an integrated high-fidelity audio system in this space.

In addition, it is preferable to have the flexibility of choosing between a wall mount and a pedestal mount. A pedestal mount is used when a flat screen is placed on top of a flat surface, such as found on the top of a piece of cabinetry. In some instances a user will prefer to use a pedestal mount. The present invention accommodates this desire by allowing the integrated mount and audio system to be attached to a pedestal, rather than being hung on a wall.

BRIEF SUMMARY OF THE INVENTION

The present invention comprises a video display mount incorporating an integrated audio system. The mount may be attached to a wall. Alternatively, the mount may be attached to a pedestal so that the display and associated audio devices may be placed upon a flat surface. A main bracket and television bracket of suitable design are included. The two components are preferably designed to easily engage so that the user may attach the video display to the wall or pedestal without the need for complex operations.

The main bracket mounts an electronics/subwoofer assembly. This assembly houses an audio amplifier (which may be a sophisticated frequency splitting device such as a PRO/LOGIC system). The assembly also includes a low-range speaker or speakers. A resonance chamber and bass port are preferably included in the electronics/subwoofer assembly so that the low-range speaker can accurately project the low-frequency portion of the audio spectrum. The low-range speaker and bass port may be included in the actual enclosure of the electronics/subwoofer assembly, or may alternatively be remotely located. In the event the low-range speaker is remotely located, it preferably receives a wireless signal from an R/F module located proximate the electronics/subwoofer enclosure.

One or more external speaker supports are included in the mount—preferably by attaching the supports to the electronics/subwoofer assembly. The speaker supports are preferably made adjustable so that the degree of extension from the mount may be adjusted by the user.

In the preferred embodiment a single speaker support is provided for an integrated assembly containing a left speaker, a center speaker, and a right speaker. In some embodiments the lateral location of the speakers is made adjustable. The speakers may be wired to the electronics housed within the electronics/subwoofer assembly. The signal to each speaker may also be transmitted wirelessly if desired. The result is an integrated audio/video system in which all components are located together in one aesthetically clean package.

DETAILED DESCRIPTION OF THE INVENTION

The present invention integrates a flat screen display and an external audio system into a unified assembly. FIG. 3 shows an embodiment in which the unifying component is main bracket 38. The main bracket is designed to be selectively attached to a second bracket which is connected on the flat screen display. The attachment between the main bracket and the second bracket can assume a virtually endless variety of forms. In the embodiment shown, upper flange 40 and two lower flanges 42 are provided to facilitate the attachment.

The two lower flanges are separated by a central gap. Numerous mounting slots 46 are provided to that the user may attach screws or bolts through these slots and attach main bracket 38 to a wall (as is known for prior art mounting brackets). These mounting slots 46 (or other suitable mounting features) may also be used to attach main bracket 38 to a pedestal so that the mounted display and associated hardware may be placed on a flat surface.

Enclosure mounting holes 48 are provided so that an electronics enclosure may be attached to main bracket 38. One or more openings are preferably provided through the main bracket so that audio and/or video cables may be easily passed through the bracket. In the embodiment shown in FIG. 3, a single large opening 44 is provided for this purpose.

In FIG. 4, electronics/subwoofer assembly 50 has been attached to main bracket 38. The electronics/subwoofer assembly preferably contains an audio amplifier and an integrated bass speaker mounted in a single enclosure (though the bass speaker may optionally be mounted outside the enclosure in a separate structure as well). Other components may be included. The combination of main bracket 38 and electronics/subwoofer assembly 50 is referred to as an “integration assembly.” This phrase is intended to encompass the many different ways that the electronics may be integrated with the main bracket. As one example, those skilled in the art will know that the main bracket could actually form part of the electronics enclosure (such as by having the flat plate of the main bracket be the base of the enclosure). The details of the structure and the attachment may be varied in many ways.

A speaker support is provided for at least one external speaker. In the embodiment of FIG. 4, center support 62 is the speaker support. This component is connected to the integration assembly. In the embodiment shown, center support 62 is actually connected to electronics/subwoofer assembly 50, but the connection to the integration assembly could be made in many different ways.

The speaker support is preferably adjustable in terms of extension. It can slide in and out of the integration assembly in order to raise or lower the speaker assembly. The speaker support may also be pivotally adjustable.

In some embodiments speaker assembly 122 may only include one speaker (such as the center channel speaker). However, in the embodiment of FIG. 4, multi-channel speaker assembly 122 contains three speakers. Speaker assembly 122 is attached to center support 62. The three speakers included in the assembly are: left channel speaker 22, center channel speaker 16, and right channel speaker 20. Tweeter 130 may also be provided. Electronics/subwoofer assembly 50 contains (or is connected to) another speaker intended to handle low frequencies.

The electronic devices within electronics/subwoofer assembly 50 preferably divide the available audio signals into the left, center, and right channels. The low frequency speaker (“subwoofer”) preferably transmits the low frequency audio for all the channels—since low frequency audio does not tend to be directionally specific.

Multi-channel speaker assembly 122 preferably contains additional elements as well. Receiver/display 132 is a small video display (such as a back lit color LCD) which provides information as to the status of electronics/subwoofer assembly 50. For example, the display can inform the user of the current Bass and Treble settings, as well as the active mode. The receiver/display preferably also includes a remote control receiver for receiving signals sent by a remote control. Electronics/subwoofer assembly 50 will be concealed behind a flat screen television when the device is in operation. Receiver/display 132 is preferably located below the bottom of the television so that it will be accessible to remote control signals intended for the electronics/subwoofer assembly. The receiver/display is electrically connected to the electronics/subwoofer assembly so that data may be freely exchanged between the two.

It is preferable to provide an electronics/subwoofer assembly which may be attached to the main bracket before the main bracket is attached to the wall or a pedestal. FIG. 4 shows such a version. The reader will note that electronics/subwoofer assembly 50 does not obstruct the mounting slots 46 on main bracket 38. Thus, a user is able to take the entire assembly shown in FIG. 4 and attach it to a wall (or pedestal) by passing several bracket mounting bolts 36 through the mounting slots 46 in main bracket 38. This may be done before or after the supports and associated speaker assemblies are installed.

Once the main bracket is in position, the user will wish to attach the flat screen display. FIG. 5 shows flat screen display 10 from the rear. The rear of such a television typically includes four or more threaded receivers 66. These are strong mounting points provided for the attachment of the television to a supporting bracket.

The rear of the television typically also includes A/V connection block 70 and power connection 68. The power connection allows a power cord to be plugged in. The A/V connection block typically provides for the connection of multiple cables of multiple types, including: HDMI, DVI, component video, S-video, composite video, RGB/VGA, and digital optical. The mounting system should provide access to the AN connection block and the power connection.

The physical connection made between the television and the main bracket can assume a virtually endless variety of forms. Thus, the embodiment shown in FIGS. 6, 7, and 10 is properly viewed as exemplary. In the embodiment of FIG. 6, a pair of TV brackets 72 is connected to the back of flat screen display 10 by passing TV bolts 74 through the TV brackets and into the threaded receivers 66 in the back of the TV.

In FIG. 7, a gripping bracket 76 is shown attached to each of the TV brackets 72. Each gripping bracket pivots around a locking screw 82 which is passed through a hole through the gripping bracket and the TV bracket. The upper portion of each TV bracket includes a pivot bracket 86 with a slot. The upper portion of each gripping bracket 76 is secured by passing a locking screw 82 through the pivot bracket and through a hole in the upper portion of the gripping bracket. Nuts 84 are engaged by the locking screws.

The reader will thereby appreciate that each gripping bracket 76 may be pivoted with respect to its connected TV bracket 72. The desired pivot position may then be secured by tightening the appropriate locking screw 82. The design shown allows the reader to adjust the tilt of the television after it is attached to the main bracket—as will be explained subsequently.

The two gripping brackets 76 are provided with features allowing them to be fastened to main bracket 38. The reader will note that the upper portion of each gripping bracket has an extension extending toward the rear. This extension includes an upper notch 78. The lower portion of each gripping bracket likewise includes a lower notch 80. The upper notches are sized and positioned to slip over and engage upper flange 40 on main bracket 38 while the lower notches are sized and positioned to slip over and engage lower flange 42 on main bracket 38. The notches preferably have a tapered entry, fillets, or other similar features to help the user engage the gripping brackets with the main brackets.

Turning now to FIG. 8, the reader will observe that main bracket 38 with its attached electronics/subwoofer assembly and speaker assembly has been attached to a wall. The appropriate mounting brackets (TV brackets and gripping brackets) have been attached to the rear of flat screen display 10. The user moves the flat screen display toward the integration assembly as shown by the arrows. He or she slips the upper notches 78 over the upper flange 40 and the lower notches 80 over the lower flange 42 in order to attach the TV to main bracket 38.

FIG. 9 shows the assembly with flat screen display 10 in position. Multi-channel speaker assembly 122 is positioned by sliding it up or down to the position the user desires. Prior to installing the TV the user will typically extend center support 62 to move the speakers well clear of the TV. Once the TV is in position and adjusted, the user may then push the speaker assembly up against the perimeter of the TV and lock it into position using a suitable locking feature. Alternatively; center support 62 may include frictional or other features which allow it to be adjusted but maintain position once the adjustment is made.

FIG. 10 shows a side elevation view of the assembly mounted on the wall without multi-channel speaker assembly 122. Main bracket 38 is attached to wall 88. The reader will observe how the notches in the gripping brackets are engaged over the upper and lower flanges in main bracket 38. The reader will also observe how the tilt of the TV may be adjusted without removing it from main bracket 38. Tilt may be adjusted by reaching in from the side and loosening locking screws 82, repositioning the TV, and then retightening the locking screws.

FIG. 10 shows how electronics/subwoofer assembly 50 neatly fits into the available space between flat screen display 10 and wall 88. Room is also available to connect the electronics/subwoofer assembly 50 with the TV, if the installation is a type requiring such a connection. In the example shown, connector cable 90 connects electrical components within the electronics/subwoofer enclosure to flat screen display 10.

The specific design of the mounting bracketry is not significant to the present invention. Thus, the reader should bear in mind that the invention includes many different types of mounting arrangements that may appear and function in different ways from the illustrated embodiments.

Likewise, the design of the electronics enclosure may assume many forms. However, as it may aid the reader's understanding, a detailed description of a few embodiments will be provided. FIG. 11 shows an exploded view of electronics/subwoofer enclosure 50. Chassis 94 contains the components. It is covered by lid 92, which may be snapped or screwed into place. These components may be made of fiber-reinforced thermoplastic, metal, or other suitable materials.

FIG. 12 shows chassis 94 with the lid fully removed. The chassis includes interior bulkheads surrounding amplifier 116. In the embodiment shown, the speaker intended to handle the lower frequencies is actually attached to chassis 94 (subsequent examples are described in which this is not the case).

Speaker 96 preferably performs the role of a “subwoofer,” meaning that it is designed to handle relatively low frequency sounds. These frequencies are generally regarding as lying below about 300 Hz, and more commonly below about 200 Hz. It is sometimes alternatively referred to as a “bass speaker.” A bass speaker is preferably capable of handling frequencies in the range of about 20 Hz to about 200 Hz. For some applications the range will be more narrow, particularly on the low end. In fact, it has been found that a speaker capable of handling frequencies down to about 30 Hz produces a good result.

In the embodiment of FIG. 12, the output of bass speaker 96 is open to the interior of the chassis. The interior forms a resonance chamber 98. The chassis also includes bass port 100 bounded by port wall 102 and port wall 104. The bass port is positioned to emit relatively low frequency tones generated by bass speaker 96.

The chassis includes other features as well. In the embodiment shown, the speaker support (center support 62)) is attached to the electronics/subwoofer assembly itself. This need not always be the case as it could be attached directly to main bracket 38 or some other component. However—in the embodiment shown—center support 62 is slidably and pivotally received within center receiver 110. Likewise, left support 58 and right support 60 are designed to slide in and out of chassis 94. The left support may be used to mount a left speaker assembly while the right support may be used to mount a right speaker assembly.

As stated previously, the receivers used for the speaker supports are preferably equipped with frictional features which allow adjustment but tend to retain the speaker assembly in position once the user releases it. One example of a frictional fit is to make the speaker support tubular and provide the receivers with NYLON bushings which fit tightly around the tubes.

Other components may be contained within the chassis. Power supply 112 provides power to amplifier 116. R/F module 114 may be provided to supply wireless outputs to some or all of the speakers. The connections between the audio amplifier and the left, right, and center speaker assemblies may be hard-wired, wireless, or a mixture of the two. The bass speaker may optionally be remotely located—in which case the R/F module 114 is preferably used to wirelessly transmit the bass portion of the sound output to the remote bass speaker.

Amplifier 116 may assume many forms. In some instances it may be a pass-through device which simply passes through the channel-specific signals received from an external surround-sound amplifier. In other instances it may itself be a sophisticated surround sound amplifier which receives an input signal from a cable or satellite feed and splits that signal into the appropriate channels, including, left, right, center, and rear.

In some versions the amplifier may receive its input from the flat screen display. In other versions the amplifier will receive its input from an external cable or satellite decoder (or other video/audio data source) with no connection being made between the amplifier and the TV itself.

Other features may be added to the integrated system. FIG. 13 shows an embodiment in which suspended shelf 118 has been added beneath multi-channel speaker assembly 122 (Note that a conventional cover 134 has been placed over the speakers for aesthetic purposes). The shelf may be attached to a suitable point such as center support 62 or the speaker assembly itself. Another component, such as a digital video recorder, may be placed on the shell In some embodiments the electronics/subwoofer enclosure will include electrical connections for many different types of components, including DVR's and DVD players.

The specific speaker configurations and positions shown in the invention should not be viewed as limiting. In some embodiments the speaker assembly could be placed above the flat screen display or even to one, side. It is also possible to include multiple, separate speaker assemblies. In the embodiment of FIG. 13, left speaker assembly 52 and right speaker assembly 54 are included.

As disclosed previously, main bracket 38 may be configured to mount to a wall or to a pedestal. It is even possible to provide a main bracket which can be optionally attached to either a wall or a pedestal. FIG. 14 shows an embodiment in which the main bracket has been attached to pedestal 136 and the entire assembly has been placed upon a horizontal surface. More details regarding an embodiment of a pedestal mounting system are disclosed subsequently.

FIG. 15 shows an alternate embodiment in which a single speaker assembly is used and in which the left and right channel speakers may be laterally adjusted with respect to the speaker support. Sliding section 144—which houses left channel speaker 22—slides in and out of center section 140. Sliding section 142—which houses right channel speaker 20—also slides in and out of center section 140. Three separate covers are provided for the speakers themselves. These are left cover 146, center cover 148, and right cover 150. As those skilled in the art will know, the covers are made from a material which is visually opaque but is “noise transparent” so that the covers do not appreciably alter the noise produced by the speakers.

As stated previously, the electronics/subwoofer assembly can be configured to support a wide variety of connections to other components. While these are well known in the art, FIGS. 16 and 17 provide two illustrative examples which will benefit the reader's understanding. In FIG. 16, video/audio output source 152 is any device producing a video and audio signal where the two signals are intended to correspond (meaning that the audio signal is synchronized in time to the video signal being shown). Synchronization in time includes examples of a natural link—such as the spoken sounds precisely corresponding to a video image of someone talking. It may also include examples of a created link—such as a selected piece of music accompanying a video which is unrelated to the music (An example would be classical music accompanying scenes of nature). There are many different types of video/audio output sources. Examples include cable TV set top boxes, satellite TV set top boxes, and DVD players.

A typical output of such devices is a five cable array. Two of these cables carry audio while three carry video. The two audio cables are a left audio channel and a right audio channel. The three video cables carry separate red, blue, and green signals. Two audio cables 14 are connected to audio output 154. In the example of FIG. 16, these are connected to audio input 166 on electronics/subwoofer assembly 50. Three coaxial RGB cables 158 are connected between video output 156 and video input 168 on video display 10.

Thus—in the example of FIG. 16—electronics/subwoofer assembly 50 receives only the audio signal and does not receive the video signal. It may, however, be deemed more convenient to pass all five connections through the electronics/subwoofer assembly. This is particularly true where a single cable having, all five connections is used (a ribbon cable in which five coaxial cables are linked laterally). In such an embodiment the electronics/subwoofer assembly would have input jacks for all five cables and output jacks for all five cables. The video signal would simply be passed through.

HDMI cables provide a unified connection for all the video and audio components of a high definition signal. FIG. 17 shows an embodiment intended for use with HDMI cables. HDMI cable 160 connects combined output 162 on video/audio output source 152 to combined input 164 on electronics/subwoofer assembly 50. A second HDMI cable 160 is then used to connect combined output 162 on electronics/subwoofer assembly 50 to combined input 164 on video display 10. It is preferable to provide the electronics/subwoofer assembly with multiple jacks of different types, thereby allowing it to be connected in several different ways.

As explained previously, some embodiments for the electronics/subwoofer assembly will include an external bass speaker (rather than including the bass speaker in the chassis itself). FIGS. 18-20 illustrate this embodiment. FIG. 18 shows an alternate version of chassis 94. The chassis includes center receiver 110 for slidably receiving center support 62, right receiver 108 for slidably receiving right support 60, and left receiver 106 for slidably receiving left support 58. It also includes the internal audio amplifier and other components as before. However, the reader will note that the chassis contains no bass speaker. Instead, R/F module 114 is used to transmit at least the bass portion of the audio signal to a remotely located bass speaker.

In FIG. 19, integration assembly 184 includes three slidably-mounted speaker assemblies (left speaker assembly 52, center speaker assembly 56, and right speaker assembly 54). In addition, the integration assembly also incorporates separate subwoofer housing 172. The separate subwoofer housing is a free-standing unit which sits on the floor. It includes speaker 96, the cone of which is actually pointed down toward the floor. The separate subwoofer housing preferably includes one or more bass ports 178, which serve to enhance the low-frequency performance of the speaker.

Separate subwoofer housing 172 also contains a second amplifier 180, which drives speaker 96. This second audio amplifier receives power from a source other than chassis 94. As one example, it may be plugged into electrical outlet 174 using cord 176. A subwoofer housing may be placed in many locations while providing sufficient performance. Thus, one can place the separate subwoofer housing near a convenient outlet (even though this may be far from where the flat screen display is located).

Separate subwoofer housing 172 contains a radio frequency receiver 170 which receives wireless signals from radio frequency module 114 in the electronics enclosure. These signals are then fed into amplifier 180 in order to drive speaker 96. The reader will thereby observe that the embodiment of FIG. 19 discloses an integration assembly in which the bass speaker is remotely located.

FIG. 20 schematically depicts the operation of the embodiment of FIG. 19. Separate subwoofer assembly 172 is of course still part of the electronics/subwoofer assembly (and part of the integration assembly). However, because it is remotely located, it is preferable to have the communication between chassis 94 and separate subwoofer assembly 172 assume the form of a wireless communication. Thus, R/F module 114 transmits singles to R/F receiver 170. A second audio amplifier 180 receives and processes these signals in order to drive speaker 96.

Although it is not shown, the first audio amplifier within chassis 94 must also be plugged into a power source. This will generally be an AC electrical outlet. Second audio amplifier 180 must likewise be plugged into a power source. This will generally also be an AC electrical outlet (which may or may not be the same outlet used to power the first audio amplifier).

The use of wireless communications between the integration assembly and a remotely located subwoofer housing may be expanded to include connections to two, three, four, or more remotely located speakers. All of these remotely located speakers may be powered by AC line power if desired. FIG. 22 shows a plan view of a room incorporating many remote speakers. Flat screen display 10 is mounted to an integration assembly as described previously. Chassis 94 contains R/F module 114 which may be used to transmit signals to many remote speakers (The R/F module should be viewed as exemplary, as the term “wireless” is intended to encompass transmission methods beyond radio, including light based transmissions).

In this embodiment the integration assembly includes right channel speaker 20, left channel speaker 22, and an integrated subwoofer contained within chassis 94. A center speaker assembly (not visible in the view) is also connected to chassis 94. Five remote speakers are also included. These are: separate subwoofer housing 172 (which contains a second subwoofer in addition to the one housed within chassis 94), front right speaker 196, front left speaker 198, rear right speaker 200, rear left speaker 202, right side speaker 204, and left side speaker 206. The combination shown includes more speakers than would be employed in a typical installation. It is intended to illustrate the many possibilities (though the reader should note that even more speakers and combinations are possible. The electronics within chassis 94 are preferably configurable to allow a wide variety of speaker combinations. Some of these combinations are described in the following table:

TABLE ONE
Name  Description
“5.1” 3 speakers mounted to the integration assembly, plus two remote
      side speakers, plus subwoofer in the integration assembly
“5.2” 3 speakers mounted to the integration assembly, plus two remote
      side speakers, plus one subwoofer in the integration assembly,
      plus one remote subwoofer
“7.1” 3 speakers mounted to the integration assembly, plus two remote
      front side speakers, plus two remote rear side speakers, plus
      subwoofer in the integration assembly
“7.2” 3 speakers mounted to the integration assembly, plus two remote
      front side speakers, plus two remote rear side speakers, plus
      subwoofer in the integration assembly, plus one remote subwoofer

Other combinations are possible. The present invention encompasses all the combinations described and many others as well. Any speaker may be connected using wires or may be connected using a wireless connection (such as a radio frequency connection). It is typical to use wires to connect the center speaker. It is typical to use a wireless connection for some or all of the other speakers.

As mentioned previously, the present invention preferably allows the user to, optionally attach main bracket 38 to a wall or to a separate pedestal. FIG. 21 shows an embodiment of a pedestal configured to attach to the main bracket. Aside from the pedestal, all other components are the same as the embodiment shown in FIG. 19. Main bracket 38 mounts electronics/subwoofer assembly 50. Three speaker assemblies are mounted to the electronics/subwoofer assembly.

Gripping brackets 76 are connected to the rear of flat screen display 10 (as shown in FIG. 7). Gripping brackets 76 are selectively attached to main bracket 38 (as described previously with respect to the wall mounted version). In this embodiment, however, the main bracket is not attached to the wall. Instead, four pedestal bolts 194 are used to secure main bracket 38 to bridge 190. Bridge 190 is connected to adjustable mount 192. Adjustable mount 192 is connected to column 188, and column 188 is connected to base 186. Base 186, column 188, adjustable mount 192 and bridge 190 are collectively referred to as pedestal 136.

In operation, the user attaches main bracket 38 and the other components to the pedestal. The user attaches the gripping brackets to the back of the flat screen display. The user then “hangs” the flat screen display on the pedestal by attaching gripping brackets 76 to the flanges on main bracket 38.

Adjustable mount 192 is preferably able to slide up and down with respect to column 188. This feature allows the user to adjust the height of the flat screen display (and other components) after the assembly is completed. A latching mechanism is preferably provided to lock adjustable mount 192 in position once the desired height is achieved.

The reader should note that the various features of the multiple embodiments disclosed may be mixed and matched to create many more permutations. The invention is by no means limited to any particular embodiment or group of embodiments.

The preceding description contains significant detail regarding the novel aspects of the present invention. It should not be construed, however, as limiting the scope of the invention but rather as providing illustrations of the preferred embodiments of the invention. Thus, the scope of the invention should be fixed by the following claims, rather than by the examples given.
